The Cisco ATA186-I2-A is a 2-port analog telephone adapter (ATA) that enables traditional analog telephones and fax machines to operate over IP-based VoIP networks. It converts analog voice signals into digital packets for transmission over Ethernet networks, making it a cost-effective solution for integrating legacy telephony into modern IP infrastructures.
This specific I2 variant features complex impedance (270Ω + 750Ω // 150nF), making it suitable for regions where this impedance standard is required.
Key Features
- Converts analog phones and fax machines to VoIP
- 2 × RJ-11 FXS ports (independent lines)
- Single Ethernet port (10Base-T) for LAN connectivity
- Supports voice codecs (G.711, G.729a)
- Compatible with SIP, SCCP, and H.323 protocols
- Each port supports a separate phone number
- Works with broadband connections (DSL, cable, LAN)
